SUCTION-CONTROLLED GOVERNOR.

Application filed March 26, 1928. Serial No. 264,772.

Thepres'ent invention relates to a suction controlled governor and has for its prime object to provide a unit that occupies the place between the carburetor and intake manifold and has a suitable connection at this point for controlling automatically the suction'therethrough. If desired, the gove'rnorv units may be built in the carburetor.

.Another very important object of the invention resides in the provision of a. governor of this nature which is thoroughly ef ficient and reliable in operation, extremely sensitive to the lead load variations and perinits the use of all of the available power of the engine at any speed setting.

Another very important object of the invention resides in the provision of a governor of this nature which does not interfere with the speed or throttle action of the carburetor ofthe automobile upto the speed setting of the governor, sothat by, opening the carburetor governor wide, the

- governor will maintain an even speed.

I A still further very important objectofi the invention resides in the provision of a governor of this nature, which is simple in and durable, easy to install. thoroughly ependable, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed. 1

In the drawing:

Figure 1 is a side elevation of the governor embodying the features of my invention.

Figure 2 is an end elevation thereof.

Figure 3 is a vertical section through the block of the governor, and 1 Figure 4 is a detail view of the flat valve.

Referring to the drawing in detail, it'will be seen that the numeral 5 denotes a block, which is shaped to fit between the carburetor and intake manifold and has openings 6 to receive the usual bolts to secure the carburetor and intake manifold together. This through, registering with the passage in the intake manifold. A shaft 8 is journaled in the block 5, and extends through the bottom of the passage 7, adjacent the end adapted to communicate with the intake manifold. This shaft is split in the portion disposed in the passage 7 for receiving the lower edge of'a flap valve 9, which is of such a size and shape as to close the passage but normall inclines toward the carburetor. The sha t 8 extends out through one side of the block 5 and secured thereto is a crank 10, which extends in an opposite direction from the shaft than the flat valve 9. On this crank 10, there is anchored, by means of a bolt or in any other suitable manner, as at 11, a plurality of leaf springs 12. The leaf springs 12, adjacent the crank 10 is shorter than the other, said others gradually increasing in length.

The ends anchored by the bolt 11 are in abutment,- but the remaining portions of the springs diverge from each other, as is clearly indicated in Figure l. A plate 14 is secured to one side of the block 5 and has an arcuate upper edge with a series of notches or teeth, as indicated at 15. A- stop arm 16 is pivoted at its lower end, as at 17, on the plate, and at its free end is provided with a stop projection 18. A spring pressed catch 19 is pivoted as at 20 on the arm 16 and has a lateral member 21 engageable in the notches formed by the teeth 15, the spring 22 being attached to the catch and to the arm. The longest spring is abuttable with the projection 18. The shortest spring is abuttable with a stop arm 23, fixed as at 24 to the plate 14.

- The valve leans toward the passing air which tends to catch the valve, raise it, and close the passage. As the valve tends to close the passage, it crowds the springs together against the speed regulating stop arm 16, until their tension equals the pull of the valve which checks the speed of the engine. When the load the engine is pulling becomes greater, the speed of the engine will naturally become slower, if the throttle is v equals the pull of the valve once again. block 5 is provided with a passage 7' there- This action is even and uniform and will maintain an even engine speed.

It can readily be seen that as the surface of the valve becomes less and less angular ferent adjusted positions by means of the catch 19, and thus the speed can be fixed as desired. The stop arm 23 catches the shortest spring and prevents the valve from falling so low that the suction of the air will not catch it. This governor is very efiicient. It is extremely sensitive to the least load variation, and permits the use of all of the available power ofthe engine at any speed setting. It does not interfere with the speed or throttle action of the carburetor of an automobile, up to the speed setting of the governor, and then by opening the carburetor governor wide, thegovernor will maintain an even speed on the road. This governor would be very effective for delivery car owners who do not want their delivery cars driven over a given speed. The governor is entirely dependable.

It is free from parts that are apt to get out of order. It islong lived because there are practically no moving parts. It is simple in construction, with no parts to get out of order and it requires no oil and consequently no attention. It is easily installed, requiring no complicated readjustments.

It is thought that the construction, operation, utility and advantages of the governor will now be quite apparent to those skilled in this art, without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to, without departing from the spirit and scope of the invention as hereinafter claimed, or sacrificing any of its advanta es.

ilavin thus described 111 invention, what I claim as new is:

1. In a suction controlled governor, the combination of a conduit, a valve therein and subject to movement, and a leaf spring connected with the valve, the parts of which spring are arranged to be crowded together and resist movement of the valve. T

2. A suction controlled governor of the class described comprising a block with a passage therethrough, a valve for controlling the passage, said valve being actuatable by the suction of air through the passage, spring means operably connected with the valve to overcome the operation of the valve by the suction at a predetermined point, said spring means comprising a plurality of leaf springs with diverging ends and an abutment against which one of the ends engages, said springs graduall decreasing in length from the one engagea le with the abutment.

4. A suction controlled governor of the class described comprising a block with a passage therethrough, a valve for controlling the passage, said valve being actuatableby the suction of air through the passage, spring means operably connected with the valve to overcome the operation of the valve by the suction at a predetermined point said spring means comprising a plurality of leaf springs with diverging ends and an abutment against which one of the ends engages, said spring gradually decreasing in length means for adjusting the abutment.

5. A suction controlled governor of the class described com rising a block with a passage therethroug a valve in the passage, a shaft journaled in the block to which the 'valve is fixed, a crank on the shaft, a pluanother, an abutment against which one of the springs engages, so that the springs will tend to maintain the valve inclining in a direction from which air is. sucked through the passage.
